Cuesta Pass just north of San Luis Obispo offers jaw-dropping scenery on Amtrak's Coast Starlight. In this segment of our northbound journey, we see the Sacramento Valley and much of the Sacramento headlands that are normally hidden by darkness. The train was delayed by mechanical problems, so we got to see the river as it cuts its way through the Cascade Mountains in Northern California - including a full daylight look at Mt. Shasta.
